What is #cobled LED technology?
COB LED, or chip on board light-emitting diode is the latest innovation in the field of LED technology. It provides numerous improvements and has already made waves in a few key areas, including lighting and LED display devices. Although greater reliability, energy efficiency, and image quality define most prominent advantages, many customers are still unfamiliar with COB LED display technology and the way it actually works.
#rgbkhytech COB LED Technology Explained
Chip on board (COB) technology is a method of directly mounting red, green, and blue chips onto a printed circuit board (PCB). Packaging the bare chips directly onto the PCB enables a much higher chip density while creating a flat uniform LED surface. The combination of three-color values allows the chips to achieve a higher color gamut and replicate true-to-life imagery.
In other words, with COB LED technology, the number of LEDs that can be placed in any given area of a display is way higher than with other LED packaging approaches, such as Surface Mounted Diode (SMD) and Dual in-line Package (DIP).
Benefits of COB LED Technology
With an understanding of what chip on board technology is and how COB LED technology differs from competing technologies, let’s explore what it can do.
1. Superior Pixel Pitch
Essentially, pixel pitch is a measurement of the density of pixels and refers to the distance between the center of one pixel and the center of an adjacent pixel. One of the biggest benefits associated with COB LED technology for display devices, including wall displays and other large-format displays, is precisely the improvements to the pixel pitch. The smaller the pixel pitch, the higher the pixel density thus the higher resolution. The COB LED displays can deliver the tightest pixel pitch which translates to a resolution of up to 4K.
The praised improvements to pixel pitch provided by COB technology are most noticeable when using a display up close because a smaller pixel pitch and higher pixel density will reduce the viewing distance. This means that viewers will be able to stand close to a display and still view it comfortably without noticing the individual pixels.
2. Improved Reliability
When compared to LCD, any LED display will be less impacted by issues like the surrounding environment and various lighting conditions. Once the screen has been set up, it can be used in differently lit situations, without the need to recalibrate the screen.
Among LED displays, the major benefit of COB LED technology specifically, is its improved reliability including water-proof, dust-proof and anti-collision capabilities. The previously mentioned reduction in soldering sites minimizes the possible points of failure. This translates overall to better thermal performance, facilitated maintenance, and, ultimately, peace of mind. Additionally, mounting the LEDs directly on the board also improves moisture- and dust resistance as the surface is protected by a durable clear epoxy resin.
According to the Ingress Protection (IP) rating that defines the level of protection against the ingress of solid objects, dust, and water, COB technology scores IP54 which is a high score for LED displays (by comparison, SMD scores only IP20 or IP30).
3. Great Energy Efficiency
In general, COB LED technology delivers higher energy efficiency than SMD. This is important when it comes to the total cost of operation for large format displays that are going to be used all day, every day for months and years to come.
4. Enhanced Viewing Experience
COB Technology also drives 4K resolution. This is of paramount importance for large-format displays used in places that need detailed and intricate visuals such as research institutions, engineering facilities, schools of architecture, or fine arts.
When compared to SMD technology, COB LED displays deliver a higher contrast ratio, smoother surface, and better reliability. COB LED technology can result in much-improved brightness and deeper blacks which is great for use indoors where plenty of natural light is present like car exhibition centers, architectural studios, hospitals, and other places that need images of high resolution.
The very best COB LED displays on the market, such as th RGB KHYTECH #SHD3 and #UTC Series, will combine these improvements with an excellent color gamut and higher contrast ratio, for the ultimate viewing experience and real-to-life color.

Final Thoughts
Chip on board or COB LED technology is the latest breakthrough in LED packaging technology and delivers especially great results when used in display devices. It tightens pixel pitch, boosts brightness, and improves viewing angles and viewing distances while providing greater long-term reliability and anti-collision, energy efficiency as well as better dust and moisture resistance.
